This invention relates to roofing shingles 'of the interlocking type and the present ap-` l0 means-for anchoring the exposed lower extremities of the shingle when in position on a roof.

It is well known that diiiiculty is found in securely anchoring the lowermost corners of 15 composition shingles to prevent lifting or warping of the exposed extremities under the action of wind and other weather conditions.

In the prior art the most common method of Y anchoring the lowermost corners of composition shingles is dependent upon the use of notches or slits extending inwardly from opposite points on the lateral margin of the shingles adjacent the lower corner and the placing of the marginal portions of underlying shingles in such notches or slits to thereby hold the exposed lower corner of the overlying shingle in position. This construction and arrangement has been open to the objection that the notches or slits produced a n weakening effect on the shingles and, in addition, the inserted edges of the adjacent shingles produced an abrupt bend in the material of the shingle at the inner edges of the slits and tended to tear or crack the material of the shingle and destroy its usefulness.

p The present invention consists of the use of anchoring members formed by lateral extensions or wings on the lowermost extremity of the body portion of the shingle itself, these wings extending in opposite directions beyond the contiguous lateral converging edges of the body portion of the shingle, and lying in the same plane as the body portion.

These wings are preferably of sulicient transverse length to extend in flat position beneath portions of the bodies of two juxtaposed lunderlying shingles of the preceding shingle course to hold down the weather corner of the shingle. In other words, instead of impairing the usefulness of the shingle by placing notchesl or slits therein, I achieved the desired function by the provision of lateral extensions or by a lateral expansion of a corner portion of the shingle to thereby provide anchoring tab members which do not in any way detract from the strength of the main body portion of the shingle.

Various embodiments of the invention will be hereafter referred to, a number of which will disclose anchoring tab members arranged to serve only when folded to underturned position and others of which are designed to serve either in an under-turned position or in their normal position in the plane of the shingle itself.

Other features of the invention will be vhereinafter referred to.

In the drawing,

Figure 1 is a plan view of a shingle embodying the invention.

Figure 2 is a plan view showing in assembled relation a shingle of the type vshown in Figure 1 with the corner tab portion underturned into anchoring engagement with adjacent shingles.

Figure 3 is a plan View showing a modiied form of the invention.

Figure 4 is a plan view showing still another form of the invention. y

Figure 5 is a plan view showing an assembled view of shingles of the type shown in Figure-4.

Figures 6, 7 and 8 are plan views of other modifications of the invention.

Referring to the drawing for a more detailed description of the invention, in Figure 1 is shown a composition shingle 10 having a laterally extended corner portion 11 providing lateral wing members 12. The corner tab member 11 is intended to be folded back on itself on the line of fold 13 to provide an under-turned tab member, as is clearly shown in Figure 2 of the drawing. It will be seen that in a. folded position of the tab member 11, the lateral wing portions 12 underlie the adjacent edges of the adjacent shingles so that an effective anchoring arrangement of the tab member 11 with the underlying shingle 10r is provided. The tab member 11 may be provided with a reinforcing member 14 formed of sheet metal, wire, shingle,-

material'or other suitable material,V this feature of the invention forming an important part of the subject-matter of the companion .i edges of the main body portion of the shingle.

villustrated in Figures 3 to It will be seen thatfwith this arrangement an increased effectiveness of the anchoring wing portions 12 is obtained. The shingles 8 are intended to be laid fiat throughout their entire extent inv distinctionito the shin le shown in Figure 2 which has a tab memgber folded back on itself at the weather corner of the shingle. In Figure 4 of the drawing still another embodiment of the invention is shown, in which the wing portions 12 are provided with a still greater lateral extension than is shown in Figure 3 of the drawing. In forming the -`corner tab portion 11 in Figure 4, the edges 15 of the wing portions 12 are cut on a horizontal line and in alignment with each other. This form of tab member is doubly effective in that it is adapted to serve both in the underturned position of the tab member shown generally in Figure 2 of the drawing, and

also in the extended position in the same plane with the main body portion of the shingle, as is shown in Figure 5 of the drawing. It will be seen that in the arrangement shown in Figure 5, the corner wing portions 12 of the tab member 11 underlie the adjacent flanking shinglesl 10 and at the same l time provide for a downward extension of vinstance Figure 6 of the drawing,

the corner tab portion 11 of the overlying shingle 10.

A Various forms may be given to the anchor-y ing tab member 11 other than the particular Aformation sho'wn in Figures 4 and 5. For

the corner portion may have an angular recess 15 formed therein to provide an attractive and distinctive-appearance to the exposed portions of the shingles when in place on a roof. It will be clear that a recess in this portion 'of the shingle affects in no way the strength of the' shingles.

Another form of the invention is shown in Figure 7 of the drawing in which the tab portion 11 has a rounded or curved formaa distinctive appearance. It will be seen that in this embodiment of the invention, as well as in the various other forms already referred to, the fundamental lateral extension of the body portion .of the shingle itself is the important feature of` the construction.

In the form of the invention illustrated in Figure 8, the weather corner portion of the shingle is provided with a pair ofpfingerlike lateral projections or wings whose outside `edges may lie substantially at ninety degrees to each other and whose upper or inside edges slope in a downward direction toward tne body of the shingle.

What is claimed is: 1'. A flexible shingle having a corner portion provided with relatively long and` narrow flanking projections separated for aportion of their length from the adjacent diverging edges of the shingle by slots whose widths are substantially equal tothe thickness of a shingle, the outer edges 'of the projections being substantially parallel to said diverging edges, and the combined widths being substantially less than the width of the interposed corner portion of the shingle.

2. A flexible shingle having a corner portion adapted to extend downwardly and provided with inger-like lateral projections whose outside edges lie substantially at ninety degrees to each other and whose inside edges form narrow slots with relation to the adjacent diverging edges of the shingle. v

3. A iexible shingle of composition roofing material comprising a substantiallyrectangular` extent and adapted to be laid with one corner to the weather and provided at the apex of said weather corner with wings extending laterally in opposite directions beyond the contiguous lateral body, and lying in mainder of the shingle, said wings being of suicient transverse length to extend in flat position beneath prtions of the bodies of converging edges of the` the same plane as the rebody, flat) throughout its entire l i als two juxtaposed underlying shingles of theY preceding shingle course to'hold down the weather corner of the shingle.

4. A iexible shingle of composition roof material comprising a substantially reclng fos

tangular body, iat throughout its entire extent and adapted to be laid with one corner to the weather and provided at the apex of said weather corner with wings extending laterally in opposite directions beyond the contiguous lateral. conwerging edges of the body and lying in the same plane as the remainder of the shingle, with the upper edges of said wings sloping in a downward direction toward the body of the shingle, said wings being of suicient transverse length to extend in flat position beneath portions of the bodies of Vtwo juxtaposed underlying shingles Vof the preceding shingle course to hold down thweather corner of the shingle.

5. A lroof comprising substantially rectangular iexible shingles of composition roong material laid with one corner of each shingle to the weather, and each shingle being fiat throughout its entire extent and having wings ibo positionedat the apex of its vweather corner,

iis

which wings extend laterally in opposite directions beyond the contigous lateral converging edges of the substantially rectangular 1 body of their shingle, and lying in the same 5 plane as the remainder of said shingle, said Wings being of suoient transverse length to extend in Hat position beneath portions of the bodies of two juxtaposed underlying shingles of the preceding shingle course to hold down the Weather corner of the shingles individually.
